President Donald Trump’s administration wants to agree a “cutting edge” free trade agreement with the United Kingdom “as soon as it is ready” after leaving the European Union, the U.S.’s chief trade negotiator has said.

President Donald J Trump has vowed to push for a “tremendously big” trade deal between the U.S. and UK after Brexit, despite Theresa May’s Chequers plan, which he has said could “kill” a future agreement.

The U.S.’s ambassador to the UK has warned that a bilateral trade deal between the two countries is “totally up in the air” after Prime Minister Theresa May revealed her soft Brexit plans which favour a continued trade relationship with the European Union.
